I am experience this error, it occurs repeatedly with BlueScreen error: DPC_WATCHDOG_VIOLATION on Windows PC, DLP 14.5 agent is installed, I also observe that when stop both the EDPA & WDP services, no BlueScreen error occures.
We saw this same thing. The fix was to obtain a hotfix for symantec or use 14.6 MP1.
Thanks Katie,
It was fixed post upgrade agents to 14.6 MP1
